Confused on an IF...THEN decimal # check

[kevlar129bp]

thanks mackrackit. the BoardAdd is stored in EEPROM 0, with a min value of 001 to a max value of 254. I hope that answers what your trying to ask me?

Thanks,

That is what little or no sleep does for me, makes me babbble more than usual.

If 254 is the max then how could this ever happen?

 
IF (boardadd = 000) OR (boardadd > 254) THEN

As Duncan says "I will get my hat now".

Sorry, I guess I should have noted that this routine checks to make sure you don't try to write an address to EEPROM that is >254 or is =0. So, if a user enters "A280" for example, I want that to be invalid. I hope that helps explain my goal?

Just tried it in the sim...
I entered "A300" and it returned with,
"Board received A044
Board address set to 44"

Hopefully you can see what I mean?

Thanks again,
C

Ok... Go ahead and change it to a WORD. 44 is what you are getting when it rolls over.

On that note, a word sized var won't flow over into EEPROM 1 will it? I'de like to avoid that if I could.

Thanks again,
C

It should not. Your code is making the max 254. The WORD size just lets something bigger, like 300 be seen as 300.

Thanks Dave! I get where your goin' with that now. I'm going to give it a run. Thanks so much for your help!
